What is the weight of one square meter of mild steel sheet one millimeter thick?

Question

What is the weight of one square meter of mild steel sheet one millimeter thick?

Answer 1

Density of mild steel = 7.85 g/cm3

So mass (weight) = 7.85 * 0.1 * 100 * 100

= 7,850g

or 7.85Kg

Answer 2

Of the top of my head I would estimate about 65 grams.

Figure out the volume of the sheet, width x length x thickness, then multiple that times the mass of mild steel per cubic centimeter.

Answer 3

In actual engineering practice we use 40.8 lbs per square foot of 1 inch thick uncoated (not galvanized) mild steel. That is equivalent to something like 7.8373 kg per square meter of 1 millimeter thick mild steel.

The above weight per square meter per mm is slightly less than what can be obtained from simply using the density of iron ( some references say 7850kg/m^3, some say 7870 kg/m^3) because mild steel has some carbon which makes the density slightly lighter. In fact High carbon steel such as STS have weights of only 40lbs/sq ft/in or 7.80655kg/m^2/mm.

Answer 4

The density of steel is 7850kg/m3 so a 1m2 of 1mm sheet would weigh

7850 x 0.001 = 7.85kg
